## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability trustsource-url-safety-verdict-973e515d
```

Example prompt: Before I submit my payment details, can you give me a CLEAR, REVIEW, or BLOCK verdict on https://paypa1-secure.com — I want to know if it's a lookalike or phishing site?

## When to prefer this

Use this endpoint when an agent needs a single authoritative go/no-go safety decision on a URL or domain before clicking, fetching content, submitting credentials, or executing a transaction — especially when you want domain trust, TLS validity, and typosquatting all fused into one graded answer rather than running multiple separate checks.

## Known failure modes

- Invalid or malformed URL input returns an error response
- Unreachable or non-existent domain may return degraded signals with low confidence
- Very new domains may have limited WHOIS data, reducing scoring accuracy
- Payment failure (402) if USDC balance insufficient
- Rate limiting if quota exceeded

## How this service works

Get a single CLEAR / REVIEW / BLOCK safety verdict on any URL before an agent clicks, fetches, submits data to, or transacts with it. Fuses domain trust (WHOIS age, TLD risk, DNS presence, registrar), a live TLS certificate check, and typosquat/lookalike-brand detection into one graded 0–100 answer with human-readable reasons — the go/no-go an agent can gate on instead of running and interpreting several separate checks itself.

## Output

A 0–100 trust score with a top-level verdict of CLEAR, REVIEW, or BLOCK, plus human-readable reasons covering domain age/WHOIS signals, TLD risk, DNS presence, registrar trust, live TLS certificate validity, and typosquat/lookalike brand detection.
